Well, I know you can do the following to remove the betwixt id ...

beanWriter.getBindingConfiguration().setMapIDs(false);

Then if you want to make the getId() value of your bean an attribute ...

beanWriter.getXMLIntrospector().getConfiguration().setAttributesForPrimitive
s(false);

or if you don't want to make all primitive values attribute as the above
will do ... in a .betwixt file write ...

<?xml version='1.0' encoding='UTF-8' ?>
<info>
<element name='YourElementName'>
  <attribute name='id' property='Id'/>
  <addDefaults/>
</element>
</info>

There ways to do this by code but, not familar with that approach.

Hi Jason,

instead of making up some id value, betwixt should simply stick with 
the id value that the object already provides. In other words: If a 
bean property "id" exists, it should be converted into an XML attribute 
"id" that will be referenced using "idref" if necessary.

======================================================================
public class Member {
    public long getId()
    public String getName()
    public Member getParent()
}
======================================================================
member 1:
    getId() = 1
    getName() = "John"
    getParent() = null
member 2:
    getId() = 10
    getName() = "Joe
    getParent() = <member1>
======================================================================
<member id="1">
    <name>John</name>
</member>
<member id="2">
    <name>Joe</name>
    <parent idref="1" />
</member>

Any idea how I could do this? Best regards,

-  Christian
